When you’re building a PC or upgrading your rig, there’s one less-glamorous component that’s very easy to miss, yet it’s essential for the best performance. A power supply unit is the component that gives power to every single component inside of your PC. While the RTX 3070 Ti doesn’t require loads of power, it is still important to find the best PSU for the job.
Nvidia recommends at least 650W for this GPU, but it’s always a good idea to have more power just in case you want to upgrade in the future. With that in mind, let’s take a look at the best PSUs for the RTX 3070 Ti graphics card.
RTX 3070 Ti PSU requirements
The RTX 3070 Ti has a TDP or around 300W, which means you can probably power everything in your PC with a 650W PSU and still have some headroom. If you are on a tight budget then 650W is fine, however, if you can squeeze a 750W or 850W PSU into your build, it may be overkill, but it will be a better investment. PSUs last a long time, with lengthy warranties, so if you think you may upgrade your PC in the next decade, consider a more powerful PSU that fits that future.
